  1. Citrix NetScaler SD-WAN 2 October 2017

  2. Citrix NetScaler SD-WAN NetScaler Software-Defined Wide-Area-Network (SD-WAN) solution: • Optimizes the delivery of web applications, cloud-based services, virtual desktops, enterprise applications, and mobile services • Combines software-defined WAN intelligence with WAN optimization • Provides reliable, secure connections across the enterprise WAN • Provides enhanced support for Citrix XenDesktop and XenApp • Available as physical appliance or virtual appliance

  3. Benefits of an SD-WAN Solution • Network Traffic Routing – Intelligent routing of traffic on the fastest available paths between any two points • Quality of Service (QoS) – Provide better QoS for high priority applications • Security – Software configured to allow improved network security • Administration – Simplified administration for remote and branch offices • Lower Cost – Can leverage low-cost/flexible Internet and 4G networks in place of higher cost multiprotocol-label-switching (MPLS) links

  4. Important Considerations Selecting a SD-WAN Solution • Resiliency and Failover – How quick is failover, reliability of packet delivery, real-time detection of outages, and dynamic failover path selection • Prioritization and QoS – Ability to prioritize applications, bandwidth reservation, packet duplication, and dynamic point-to-point connections • Security – Common features include IP-SEC encryption, some include rotating keys and splitting traffic across multiple links. A few products can also inspect SSL/TSL encrypted tunnels • Administration and Troubleshooting – Advances solutions provide easy-to-use GUI interfaces and algorithms to select paths automatically

  5. Addressing WAN Pain Points Wide Area Networks (WANs) suffer from many issues including: • OutagesCitrix SD-WAN can automatically switch in milliseconds to flexible internet and 4G network connections • Packet loss Citrix SD-WAN has the ability for better QoS for high-priority applications and provides visibility into WAN paths to help administrators troubleshoot performance issues • Congestion - Citrix SD-WAN has the ability route traffic on the fastest available paths between any two points • Difficult to administer – Citrix SD-WAN has the ability simplified administration for remote and branch offices • Cost - Citrix SD-WAN can leverage low-cost and flexible Internet and 4G LTE network connections in place of networks multiprotocol label switching (MPLS) links

  6. Who Benefits from a NetScaler SD-WAN? Customers should consider a NetScaler SD-WAN solution if they: • Support remote workers, flexible working, or large mobile workforce • Desire to increase data center agility and automation • Have a cloud strategy in place or under development • Looking for business agility while reducing infrastructure management costs • Require infrastructure changes to support changing regulations • Current infrastructure does not support strategic initiatives

  7. Use Case for Citrix NetScaler SD-WAN Business Continuity and IT Disaster Recovery Every network is vulnerable to risk ranging from natural disasters to minor disruptions. SD-WAN availability includes the user experience where users are not forced to restart, reconnect, or log-in to applications during the failover and recovery process. NetScaler SD-WAN provides: Sub-Second WAN failover, Automatic Transition and Secure Access

  8. Use Case for Citrix NetScaler SD-WAN Improve VoIP for Business Performance and Quality SD-WANs provideVoice over IP (VoIP) applications that need optimized performance and bandwidth to provide the QoS required to function efficiently. NetScaler SD-WAN provides: Application Delivery Acceleration and WAN Bandwidth Optimization

  9. Use Case for Citrix NetScaler SD-WAN Improve Application Performance for Mobile, Remote, and Branch Users Network speed, reliability, and security are crucial as companies rely on applications that tax networks such ascloud applications, VoIP, and large video files. SD-WANs provide application acceleration and WAN optimization to ensure secure, reliable performance for all users. NetScaler SD-WAN provides: Reliability, WAN Bandwidth Optimization, Automatic Transition, and High QoS Granular Setting Control

  10. NetScaler SD-WAN vs the Competition The following are features only found on NetScaler SD-WAN • Reacts in milliseconds to small changes in network state, eliminating any degradation of user experience caused by network problems • Bonds WAN links together to provide the most efficient throughput for an application • Selects the best path for each session based on application requirements and network conditions • Detects over 4,000 applications and sub-applications for use in firewall and SD-WAN polices • Optimizes HDX traffic at the source code level, delivering the best possible XenApp and XenDesktop experience to users

  15. When to Use Physical NetScaler Appliance Choose the NetScaler physical appliances if the environment requires: • Multi-gigabit performance • High-volume SSL offload • More than 5,000 concurrent SSL VPN users • FIPS compliance • Physical device security

  16. When to Use Virtual NetScaler Appliance NetScaler virtual appliance should be chosen if: • Lab, test,or development environments • A dedicated, single NetScaler instance is needed for low volume applications • Frequently moved applications • Fast and remote deployments • High granular policy needs for each application or end user

  17. NetScaler SD-WAN Platforms NetScaler MPX - Hardware-based app delivery appliances with performance of 500 Mbps–200 Gbps Best for: • Managing web applications with multiple gigabits of traffic • Load balancing for small enterprises • Ultra-high performance web application security • Flex tenancy

  18. NetScaler SD-WAN Platforms NetScaler SDX - Hardware-based appliances with virtualization to consolidate up to 115 independently managed NetScaler instances with performance up to 200 Gbps Best for: • Consolidating multiple physical load balancers • Providing flexible multi-tenancy • Service providers requiring fully isolated tenants • Simplifying application rollouts from staging and dev environments

  19. NetScaler SD-WAN Platforms NetScaler VPX - a virtual appliance that supports all the features and functionality of a physical NetScaler, with the exception interface-related events, tagged VLANs. Supports performance of 10 Mbps – 100 Gbps Best for: • Architecting hybrid cloud infrastructures • Cloud native application load balancing for public cloud environments • Replace hardware-based load balancers • Utilizing NetScaler within non-production environments • Architecting scalable multi-tenant infrastructures • Attractive application delivery options for telco, enterprises and small businesses

  20. NetScaler Licensing • Uses Activation System/Manage License tool on MyCitrix.com • Optional Licenses include: • AppCompress, AppCache, Application Firewall, Global Server Load Balancing (GSLB), EdgeSight for NetScaler, CloudBridge, and CloudConnections • The Platinum Edition contains all supported features and therefore no additional option licenses are required

  21. Scale Up Pay-As-You-Grow Elasticity • Licensing model that provides 5x faster performance on demand with no new hardware • Allows a customer to buy only what they need today then easily scale up as demand grows • Well suited to cloud computing environments enabling quick and affordable expansion

  22. Burst Packs Allows up to 90 day conversion of NetScaler MPX hardware or VPX virtual appliance to the highest performance available for the platform • Allows customers to provision only the necessary performance for durations of limited peak traffic • Reduces capital and operational expenses to cover limited peak periods

  23. Summary NetScaler SD-WAN provides a software-driven network alternative to traditional WANs while providing superior: • Reliability • Flexibility • Security • Cost • Ease of Administration
